Abstract (en)
[origin: EP0514082A2] A method and apparatus are described for verifying handwritten, human signatures, and for permitting access to a system if such a signature is accepted. In an initializing stage, an authorized entrant submits a sample of multiple signatures (110). A first reference signature is selected from the sample (150), and a second reference signature is constructed by averaging over the sample ( 180). When a subsequent, prospective entrant submits a signature, a dynamic mismatch is calculated with respect to the first reference signature (220), and a shape mismatch is calculated with respect to the second reference signature (240). The signature is accepted if it satisfies a predetermined criterion that refers to the dynamic and shape mismatch values (250, 260). <IMAGE>
